Filed: 1929-10-21
Abstract: 345,667. Rotary engines and pumps. SHEPPARD, H. P., Granville House, The Spa, Gloucester. Oct. 21, 1929, N o s. 31945/29 and 23589/30. [Class 110 (ii).] A motor or pump comprises a rotary member such as the eccentric 10, Fig. 1, fast on the shaft and working in the upper part 11a of a closed casing 11 containing a liquid, which forms the reciprocating working link between the eccentric and a piston P reciprocating in the cylinder C. Packing means such as slides or rollers 13 prevent flow of liquid from the upper chamber to the lower 11b ; any leakage may be replaced or the amount of liquid may be regulated by an auxiliary pump excess being removed through a drainage channel R. A second drainage trap may be used above the channel R or a gap may be left between the upper and lower cylinder parts to make certain that none of the liquid enters the working space in the cylinder. The working piston may be of less diameter at its upper part P<1>, Fig. 7, than at the part where it enters the casing 11. The annular chamber B formed by the corresponding two-diameter cylinder construction is used as a buffer chamber; or the working surface of the piston may be of larger diameter than its lower end. The working cylinder C may be connected to the casing 11 by a pipe. Suitable valves or ports are provided according as the machine works as a compressor steam engine, internal-combustion engine, &c. ; Fig. 1 shows ports A, E for the admission of air and exhaust of products of an engine working on the two-stroke internal-combustion cycle using heavy fuel.

Title: An improved method of, and means for controlling polyphase induction motors
IPC: H02P1/32
Filed: 1927-11-29
Abstract: 282,368. Hunter, R. B. Dec. 15, 1926. [Convention date]. Systems for alternating-current motors only; controllers with auxiliary switches.-In the process of starting and accelerating an induction motor the stator windings 5, 6, 7 are first switched-on to the supply conductors L<1>, L<2>, L' in star connection by the closure of an electromagnetic switch M. After a short, period of acceleration a series magnet R<1>, which opened a pair of contacts 13 under the initial rush of current, closes them again and thus energizes an electromagnet 12 to operate a change-over switch DY, whereby the stator windings are put in delta connection for the remainder of the accelerating period. At the close of the accelerating period a suitably calibrated series magnet R<2>, which closed a pair of contacts 14 with the first rush of current, opens them again and thus de-energizes the magnet 12, whereby the motor connections are changed back to start for normal running. An electromagnetic reversing switch for stopping the motor quickly by " plugging " may be added to the arrangement. As an alternative to the preferred use of series magnets for controlling the automatic changes of connections, contact-members retarded by a dashpot may be mechanically operated by the line-switch M.
Patent GB-1193713-A (GB)
Title: Colour Video Signal Generating Apparatus
IPC: H04N9/077
Filed: 1967-07-13
Abstract: 1,193,713. Colour television cameras. SONY CORP. 13 July, 1967 [15 July, 1966], No. 32225/67. Heading H4F. [Also in Division G2]  Plural colour component signals are derived with the aid of a single pick-up tube 7, Fig. 1, by forming an image of a scene 1 on the tube target 4 through an optical path including a colour filter 8 and a cylindrical lens screen 9 in which the lens axes extend at right-angles to the line scan direction. The arrangement is characterized by a construction of filter 8 such that there are imposed intensity variations on at least two of the colour components in the line scan direction, the variations being such that generated signals corresponding to the two components exhibit the same carrier frequency but differ in phase whereby they may be separated in terms of phase. In one construction of filter, Fig. 3, the filter is divided into sections by two 90-degree-phase-displaced sinusoidal lines about an axis 14 which is disposed in the line scan direction. Sections G pass green light, section C green plus blue light, section Y green plus red light and sections W green plus red plus blue light. The resulting image which is formed on the tube target consists of a uniform green component together with red and blue components which vary in intensity sinusoidally in the line scan direction and repeat for each lenticule of screen 9. The red and blue variations are in phase quadrature. The tube output signal is separated by filters 22, 23 into a low frequency luminance component, consisting of the green signal together with the red and blue D.C. and Low frequency components, and a carrier component whose quadrature phase modulations are separated by detectors 24 and 25 to obtain red and blue signals. Reference signals to operate the detectors are obtained from oscillator 27 by way of a first phase shifter 30 and a second 90-degree phase shifter 31. Signals to synchronize the oscillator are produced by including an opaque strip 17D in the filter. Resulting signal components, which occur at the frequency of the colour carrier and harmonics thereof, are separated from the tube output signal by filters 26 and 29 and applied to a mixer stage 28. Filter 8 may be modified, Fig. 6 (not shown), to consist of a plurality of parallel sections similar to Fig. 3. An alternative construction, Fig. 7 (not shown), merely consists of parallel green, yellow, white and cyan strips. Alternative ways of producing signals to synchronize oscillator 27 are described with reference to Fig. 8 (not shown) in which electroluminescent light sources are combined with lens screen 9, or the shape and forms of the lenticules are modified. Reference is also made to the use of electroluminescent light sources to bias the target image so as to distinguish the signals produced by opaque strip 17D.

Title: Improvements in or relating to a nitrocellulose product and process of manufacture
IPC: C08B5/04
Filed: 1964-08-11
Abstract: Hydrocarbon-wet nitrocellulose granules are made by contacting a heated, agitated, aqueous slurry of fibrous nitrocellulose with 0.3-2.0 parts by weight, per part of nitrocellulose, of an organic liquid which is a solvent for the nitro-cellulose, removing substantially all of the solvent by distillation while continuing agitation, separating excess water from the resulting hardened nitrocellulose granules, then substantially displacing sorbed water from the water-wet nitrocellulose granules in presence of excess volatile hydrocarbon liquid, separating excess hydrocarbon, and recovering nitrocellulose granules wetted with 10-40% by weight of sorbed hydrocarbon, based on total weight. The organic liquid solvent may be a ketone or an ester, while the hydrocarbon may be aliphatic or aromatic.  Many are specified. The aqueous nitrocellulose slurry may contain 5-20% by weight of nitrocellulose, and is preferably heated to a temperature at or near the boiling-point of the organic solvent or water-solvent azeotrope.  The proportion of added solvent is sufficient to soften, but not to dissolve, the nitrocellulose, which is then converted to hardened, irregular, dense granules by distilling off the solvent at atmospheric or reduced pressure.  After removal of excess water by e.g. drainage or centrifugation, sorbed water may be displaced by slurrying the water-wet granules in excess hydrocarbon and distilling at atmospheric pressure, or under reduced or increased pressure.  The resulting free-flowing granules contain usually less than 1% by weight of water, and have a bulk density (dry basis) of 20-40 lbs. per cubic foot. In examples, toluene-wet nitrocellulose granules are prepared from fibrous nitro-cellulose containing 11.0-12.6% of nitrogen, after softening with methyl ethyl ketone, methyl isopropyl ketone, or isopropyl acetate.
